Earth’s natural resources are what we are extracting from the earth. Industries, which excavate the earth’s resources, include forestry, oil extraction, and mining. Present-day society is based upon a vast consumption of non-replaceable minerals and fuels such as coal, oil and natural gasses. Other materials such as cotton, wool timber and produce, if utilized wisely can be replenished. Is the carbon dioxide level higher, due to massive amounts of forest being cut down and the levels of carbon dioxide left in the atmosphere higher? Therefore, my hypothesis is that deforestation of the Amazon rainforest leads, not only, to a reduction of the amount of carbon dioxide taken out of the atmosphere, but also to an increased release of carbon dioxide in the atmosphere. The earth’s natural resources are there for all of us to use. We need the water, food, air, energy, medicines, warmth, shelter and minerals that the earth’s natural resources give us. Therefore, keeping us fed, comfortable, healthy and alive. If we use the resources carefully then they will last indefinitely. But if we use them wastefully and excessively, they will soon run out and all will suffer. The excessive waste is happening in our rainforest every minute of every day of every year. Roger Stone and Catherine Caufield report that pristine rainforests have become battlegrounds between nature and those bent on imposing their order. (Caufield & Stone, 1985) “The casualty list is frightening: Indians who have been displaced by meaningless roads that go from nowhere to nowhere; thousands of acres of erstwhile rainforest, now gray moonscape, foraged by skinny…...

... Causes of Deforestation: Agriculture - As demands on agricultural products rise more and more land is brought under cultivation for which forests are cleared, grass-lands ploughed, uneven grounds leveled, marshes drained and even land under water is reclaimed. Plantations and commercial agriculture - A major force behind deforestation is commercial agriculture: Wealthy companies clear large areas of forest to be converted into farmland. Commercial agriculture such as: Palm oil and acacia trees, cattle ranching, soybeans, etc. Urbanization - Industries and towns are developing in former rainforest. Hydroelectric power - Rivers are dammed and huge areas of forest are flooded as a result. Transport - Transport networks are built through the forest to link settlements. Industries - Forest are cleared to support industrial activities and extraction of resource, Two main types are: Logging for timber and mining for minerals. Forest Fires - Fire is often used to clear forested land, as it is cheaper than employing laborers and bringing in machinery to remove the trees and vegetation. The vegetation is cleared and left to dry out, then the area is set on fire. Burning of forest has taken place on a small scale for many thousands of years, by small groups of subsistence farmers, this is known as slash and burn agriculture. Mining - Large areas of forest are cleared for the open-cast mining of minerals such as iron, gold and copper. Roads - Road shave......

...UNIT I DEFORESTATION CHAPTER 1 What is deforestation? Deforestation is the removal or damage of vegetation in a forest to the extent that it no longer supports its natural flora and fauna. In other words, deforestation can be defined as the transformation of forest land to non-forest uses where forest land includes lands under agro-forestry and shifting cultivation, and not simply closed canopy primary forests (FAO/UNEP, 1982). However, this definition does not include “logging”. More inclusive was Myers’s 1980 definition, where deforestation refers, “generally to the complete destruction of forest cover through clearing for agriculture … [so] … that not a tree remains, and the land is given over to non-forest purposes … [and where] very heavy and unduly negligent logging … [result in a] … decline of biomass and depletion of ecosystem services … . So severe that the residual forest can no longer qualify as forest in any practical sense of the world.” Alan Graigner (1980, AS quoted in Saxena and Nautiyal, 1997) asserts that selective logging does not “lead to forest clearance and does not constitute deforestation”, whereas Norman Myers (1980, 1993) thinks that logging is crucial because, although it may only affect a small proportion of trees per hectare, it damages wide areas and is the precursor of penetration by the forest farmers. For the purpose of this study, the FAO’s latest definitions (1993) will be used. The FAO defines forests as “ecosystems with a minimum...

...Deforestation Jason Hennessee Axia College of University of Phoenix Deforestation “Dad! Dad! It’s opening day! Can we please go to the forest to watch the boats race?” Junior, age 10, was very excited about the idea of watching the boats race from the relative quiet and shade of one of the forests to border the river. “Sissy already has the car packed for the trip, and I think she even remembered to grab the charcoal this time!” Dean opened one eye. Seven in the morning was a bit early to leave for the boat races thirty minutes away when they started at nine. But, such was Junior’s excitement that Dean forced himself out of his bed earlier than he planned on. “Ok, son. Let’s check Renee’s packing and we’ll see about weather and conditions. Does Mom have her work finished yet?” Anne appeared framed in the bedroom door. “Yeah. I have some more reading to do, but I can do it at the site. The races are not my favorite thing, but you’ll need my help if the kids want to get wet. However, there is something I need to talk to you about. Junior, honey, please go make sure you have a cooler full of water and juice for us today.” Off like a shot, Junior dashed out of the room and Anne went in, closing the door behind her and lifting Dean’s laptop to the bed. “Dean, I think the forest is gone. Check this out.” Dean read the headlines and cutlines of the pictures and articles that Anne showed him. He shook his head as one by one they all told a devastating...

...DEFORESTATION 1. Introduction The year 2011 is ‘The International Year of Forests’. This designation has generated momentum bringing greater attention to the forests worldwide. Forests cover almost a third of the earth’s land surface providing many environmental benefits including a major role in the hydrologic cycle, soil conservation, prevention of climate change and preservation of biodiversity. Forest resources can provide long-term national economic benefits. For example, at least 145 countries of the world are currently involved in wood production. At the same time, Sufficient evidence is also available that the whole world is facing an environmental crisis on account of heavy deforestation. Nobody knows exactly how much of the world’s rainforests have already been destroyed and continue to be razed each year. Deforestation is a major issue in today’s era. In the name of modernization, man has cut down trees in great numbers that has lead to the destruction of great forests and the lives of many animals and plant species. We fail to realize that trees are the most important aspects of our planet and the existence of tress does play a vital role. 2. What is Deforestation Deforestation is the conversion of forest to an alternative permanent non-forested land use such as agriculture, grazing or urban development.

...Deforestation Environmental Science SCI-204 iLab 1 People relay on products from rainforest everyday and never realize it. Today, people around the world use woods that come from rainforest for products like desk, flooring, instruments, and many other products made from exotic woods. “Tropical forests yield some of the most beautiful and valuable woods in the world, such as teak, mahogany, rosewood, balsa, sandalwood and countless lesser-known species.” (Rainforest Alliance, 2014) Many medications are made up from plants and trees that are only found in rainforest. “Some 120 prescription drugs sold worldwide today are derived directly from rainforest plants.” (Talk, 2014) Many food products come from rainforest. Things like coffee beans, bananas, nuts, chocolate, and spices all can be found in the rainforest. “At least 3000 fruits are found in the rainforests; of these only 200 are now in use in the Western World.” (Taylor, 2012) Another product people use everyday is oxygen. The Amazon produces more than 20% of the world’s oxygen. “The Amazon Rainforest has been described as the "Lungs of our Planet" because it provides the essential environmental world service of continuously recycling carbon dioxide into oxygen.” (Taylor, 2012) The next time you inhale, and fill your lungs with life giving oxygen be thankful to the rainforest. The rainforest has helped the world with many products, and all of them are important to everyday life. When you go to your local......

Rainforest Essay

...Amazon Rainforest is incredible. To see it, is to have an awe-inspiring experience. “The Amazon Rainforest has evolved over millions of years to turn into the incredible complex environment” (Amazon Rainforest) It is a beautiful landscape filled with some of the most beautiful animal and plant species on earth (see figure 1) .and is one of the world's greatest natural resources. The Amazon Rainforest produces about 20% of the earth’s oxygen because its vegetation continuously recycles carbon dioxide into oxygen. It has been described as the "Lungs of our Planet" (Amazon Rainforest). This rainforest is the world’s largest tropical rainforest and covers over a billion acres. The areas included would be Brazil, Ecuador, Columbia, Venezuela, and Peru. Figure 1 “Why is the Amazon Rainforest so important?” The Amazon is very ecologically important for many reasons. First of all, the rainforest has probably the largest collection of plant and animal species in the whole world. It is estimated that a single hectare (2.47 acres) of Amazon rainforest contains about 900 tons of living plants, including more than 750 types of trees and 1500 other plants (Rainforest Facts). The Amazon rainforest is considered the richest biological incubator in the world. Amazingly, the Andean mountain range and the Amazon jungle are the home to more than half of the world's species of flora and fauna; and are home to over 438,000 species, and many more are yet to be discovered (Rainforest......

...2-4-2014 | | Amazon Deforestation | | Deforestation is the loss or destruction of naturally occurring forests. It is primarily due to human activities such as cutting trees for fuel, slash-and-burn agriculture, clearing land for livestock grazing, oil extraction, and many others. Deforestation is considered to be one of the contributing factors to global climate change. It can occur around the world, even though it’s more common in tropical rainforests. Countries with significant deforestation currently or in the recent years include Brazil, Indonesia, Thailand, and parts of Eastern Europe. Though deforestation has increased rapidly in the last fifty years, it has been known to be practiced through history. Deforestation is typically done to make more land available for housing and urbanization and cattle ranching. Most of the logging industry that contributes to deforestation is done illegally, as reports from the World Wildlife Fund state. Common methods include burning trees and clear cutting, which is the controversial practice of complete removal of a given area of forest. In Brazil, you will find the Amazon rainforest. It is 5.7 million square kilometers and the largest continuous rainforest in the entire world. Since 1970, one sixth of the Amazon has been cleared mainly for ethanol production and cattle. While techniques like slash-and-burn provide a short term boost in agricultural production, rainforest soil is typically very thin and does not......

Amazon Rainforest

...The Amazon rainforest is a standout amongst the most ecologically differing districts on the planet. Its remoteness and absence of nearness to more created urban scenes has helped it make and safeguard an extensive variety of life, including roughly 30% of the known plant species in Latin America (WWF). Nonetheless, as deforestation keeps on harming this biological community and disturb the common adjust that has directed it, the impacts can to be sure be sweeping; harm to the Amazonian rainforest causes neighborhood aggravation, as well as permits worldwide outcomes. Mainly, the impacts of deforestation play both emotional and inconspicuous parts. The copious biodiversity that makes the area so remarkable additionally acts against the rainforest as more of it vanishes. Vanishing of vegetation makes progressively outstretching influences in the evolved ways of life and supplement systems; species that typically have stayed inside one area of the timberland are pushed to another basically by means of the quest for sustenance. This, obviously, just applies if the creatures' nourishment supply exists somewhere else in the woods. On the off chance that this is not the situation, the populace may confront termination because of absence of sustenance. Regardless of the fact that the organic entities have the capacity to adjust to their new region, they now put an unbalancing weight on the district. Local populaces even of the same species—and invasives are presently contending......

...when we decide to destroy and take over the Amazon rainforest. This is home not only to people but many different species of animals and vegetation. This forest provides oxygen and plants that are used for medicinal purposes. We don't have the right to invade someone's home and tell them they need to leave and force them to learn a whole new way of life that they have no clue about. I am sure that technology would be beneficial to them, but when you are used to living your whole life without technology, it is not something that will be easily accepted. Everyone has a right to happiness and to be free from pain and suffering. These people have their customs and their beliefs that they pass on from generation to generation. We take away their happiness and inflict pain on them by destroying their home. On the other hand, if we relocated them, couldn't they still keep their traditions and beliefs? That is something that will always be a part of them and no one could take that from them. Some believe that there should be a line drawn and that maybe we can leave a part of the rainforest intact for the people who live there. Some say that greed is taking over and they want it all. Clearing out the rainforest would mean homes could be built and roads put in and this would open up opportunities for the people in surrounding areas. If we were to leave a part of the rainforest intact and built around it, how would the people of the rainforest feel? How would the people living in the......

...Amazon Rainforest Chavela Montano, Allison Maestas University of Phoenix Science 265 The Amazon Rainforest is the largest rainforest in the world covering over 1.4 billion acres. The Amazon Rainforest is so large it spreads across a few countries; these countries include Brazil, Peru, Venezuela and Columbia, just to name a few. The Amazon Rainforest is home to 10% of the world’s wildlife, and 20% of the world’s bird population. The Amazon Rainforest is the world’s largest producer of oxygen because of the variety of plants that can be found in the rainforest. The Amazon is not a popular destination for tourists because of the wildlife, the drug cartel and so many unknown circumstances that surround the Amazon. The climate is very humid, hot and wet; definitely not something tourists enjoy. Many people who live in the Amazon Rainforest live off of the land; therefore they are experts when it comes to agriculture. The only problem with the agricultural community is the fact that most of the communities are tribes and they use traditional methods when it comes to farming. Some tribes use the slash and burn method when it comes to farming in the rainforest. This is adequate for a village, but not for mass production. Tribes typically will farm the land until it fails to produce more food, due to the depletion of minerals in the soil. When this happens, the tribe will relocate so they can find fresh soil to start a new farm. This has a huge......

...Deforestation Identifying the Problem Deforestation is the removal of related ecosystems or rainforests into ecosystems that are less biodiverse such as croplands, pastures, or plantations. Also, more people need wood to make furniture, houses, and many more everyday things. An estimated 18 million acres of forest are lost each year. Believe it or not but in 100 years if the current rate of deforestation continues all forests will be gone. This will cause terrible effects on the global climate and it will get rid of the majority of plant and animal species on the planet. Deforestation is mainly due to our acts that are totally against the laws of nature. To create new land area for people forests are being destroyed. This trend shows the greed of humans and the increasing needs. There are two different types of deforestation: Clear Cutting and Slash and Burn. Clear Cutting is cutting down a large area of trees that are standing at the same time. Slash and Burn is when people cut down all the foliage in a forest and burn it to access the nutrients. (4) A lot of the countries with high amounts of deforestation are the ones that are developing. For the countries to grow and develop their economies they need access to more resources, employment of people, logging to manufacture more timber products, and agricultural expansion. The solution to getting all these positive things is deforestation. The world’s highest rates of deforestation are happening in the......

...Deforestation Deforest is defined as the cutting down and removal of all or most of the trees in a forested area. ( The action of deforestation damages the quality of the land. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. (Wikipedia) Deforestation affects the environment greatly and is one of the primary contributors to climate change. When deforestation occurs, carbon dioxide is released and remains in the atmosphere. As the carbon dioxide accumulates it catches radiation, which leads to heat. Oxygen doesn’t hold radiation like greenhouse gasses do. The heat that is produced is considered global warming. Trees store carbon and when it is cut down that carbon is released into the air. According to the World Carfree Network (WCN), cars and trucks account for about 14 percent of global carbon emissions, while most analysts attribute upwards of 15 percent to deforestation. ( Another aspect of the environment that deforestation affects is the water cycle. Trees help perpetuate the water cycle by returning water vapor back into the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts. (Society) Water vapor is a greenhouse gas. The flow of water vapor and carbon dioxide is disrupted directly by cutting down trees. The water that the trees draw from the ground is eventually emitted into the air. When the land is......

Deforestation of Tropical Forests

...Deforestation of Tropical Rainforests Gabriel Corbeil ENV/GEO 120 March 20, 2015 Introduction: Tropical rainforests represent an important percentage of the globes biodiversity. This ecosystem is estimated to house 50% of all plant, insect and animal life. Covering less than 7% of Earth’s surface, it nonetheless is attributed with producing 20% of our oxygen supply. This unique biome arcs like a green arrow along the equatorial line. Its primary locations are South America, Central Africa and South-East Asia. Each region is facing varying degrees of serious deforestation. The result being widespread loss of humid tropical forest “Between 1990 and 1997, 5.8 ± 1.4 million hectares of humid tropical forest were lost each year, with a further 2.3 ± 0.7 million hectares of forest visibly degraded.” (Achard et al. 2002) The heart of the problem lies beneath a tangled mess of socio-economic growth resulting in massive deforestation chiefly for the land. Commercial farmers using the land for cattle, soybeans, palm oil and monoculture tree farms take advantage of loose government regulations. The most common tactic for land for forest removal is “slash and burn” where existing vegetation is cut down and burned for fertilizer. This technique has major impacts on multiple cycles key to forest health. Most notably the hydrological cycle, the nitrogen cycle and the carbon cycle. If this trend continues there will be major changes in precipitation and air quality, both locally and......

Tropical Rainforest

...Tropical Rainforest Hassan Gordon American Intercontinental University The Tropical Rainforest is a forest occurring in tropical areas of heavy rainfall. In the tropical rainforest most trees in the rainforest have wide buttress roots. Deforestation is a major problem caused by humans in the tropical rainforest. The government has cleared large areas of the Amazon Rainforest and encouraged people to move there. About 80% of the rainforests nutrients comes from trees and plants. Tropical Rainforest Tropical Rainforests are located around the equator, in areas with lots of rainfall, and where temperatures consistently stay near 80 degrees’ year round. Emergents are the tallest trees that are located in a tropical rainforest, which usually can stand well over 160 feet. You also have the canopy level which is a sea of leaves blocking lower levels from the sunlight. The canopy is here nearly half the animal population is, like the monkeys, birds, snakes, and also vines that lead up from lower levels that reach the sun. Then you have the shrub layer which has the most compacted plant growth, mostly plants, and ferns that do not require much sunlight to grow, then you have the forest floor that is mostly dark, and wet which contains a layer of rotting leaves and dead animals that have decomposed creating a thin mist full of nutrients. Biochemical cycles are the pathways in which the transformation, and transport of matter takes place. There are four areas categories......

...will discuss deforestation across the globe and how it affects the world’s ecosystems. Everyday, a piece of Earth’s ecosystem is demolished by human hands for the conquest for timber, minerals, and other resources. Forests cover 2% of the Earth’s surface, 6% of the landmass, and yet they house half the animal and plant species while rainforests cover twice that area. Deforestation is occurring across the globe on a scale that if it were continue at its present rate the forests could disappear within the next one to two hundred years. This raises concerns and questions. First, why should we be concerned? Second, what kind of damage could deforestation lead to animal and plant species, human existence, and to mother Earth and its atmosphere? Third, how and why the rainforests benefit the human race. To answer these questions, this paper will discuss where the most deforestation is occurring and the consequences of deforestation. Tropical rainforests are defined by two primary factors: location and amount of rainfall they receive. Rainforests receive from 4 to 8 meters of rain a year. Most of the rainfall is blocked by heavy vegetation, and water reaches the forest floor by rolling down branches and trunks. A distinctive characteristic is that the rainforests have no seasonality or no dry or cold season of slower growth. In addition, they are the Earth’s oldest living ecosystems. The rainforests are a priceless part of mother earth and their removal through deforestation would......
